README

Bash Guard

Pi extension that intercepts bash tool calls, applies deterministic safety policy checks, and then uses parallel LLM voters for commands that are not trivially safe.

See extensions/bash-guard/README.md for behavior and configuration.

Quick start

pi install npm:@accolver/bash-guard

Or install directly from GitHub:

pi install git:github.com/accolver/bash-guard

Bash Guard starts disabled by default. Enable in a session with /guard on, or opt in at startup with:

PI_BASH_GUARD_ENABLED=true pi

Development

pnpm install --frozen-lockfile --ignore-scripts
bun test
bun run check

Development checks target exact Pi 1.0.0 packages. check performs strict semantic TypeScript validation of extension source and tests (third-party declaration internals are skipped). Host packages remain optional wildcard peers, never bundled. Current validation and release evidence is under .spec-to-ship/features/pi-1-compatibility/.
